One Piece of Song Dynasty

Liang Xing said: "Yes, who doesn't want to live a happy and beautiful life at home with his family and children every day? Everyone wants to live such a good life, but if no one protects our country and our nation, we can live with peace of mind. It’s a good life, so there are always some people who need to make sacrifices. Brother Zhao, you and me, and those we brought to the Liao Kingdom, they are all included in this list. If someone can see us Han people rise again while someone is still alive, I feel that this trip in this life is worthwhile.”

Zhao Yun said with emotion: "If we can really see us Han people rise again, I am willing to take this life. In the past year or so in Liao Kingdom, I have finally seen clearly that without a strong country, we Don't even think about a good life. Just look at how the people of Liao Kingdom have lived since the Liao-Jin War. We Han people need a strong country. Only when the country is strong can we not be bullied by foreigners and our people can live a better life. Have a good life living and working in peace and contentment.”

Liang Xing nodded and said: "So what we do in Liao is very important and meaningful. Brother Zhao, let us work together for the rise of the Han people."

The more they talked, the more excited they became. In the end, their hands held each other tightly. Zhao Yun said, "Well, after talking so much, what is Brother Liang going to do about my sister-in-law? He really plans to keep her with Han Xing."

Liang Xing sighed: "Let's take it one step at a time. If it doesn't work out in the end, we can only let them stay. It's just to pay more attention to safety. But at least I sent Lei'er back, which can be regarded as alleviating a trouble. At least I have an explanation with so-and-so’s father and mother.”

Zhao Yun nodded and said: "That's all we can do for now."

The wheel of time continues to roll forward. Today, Zhao Xi and Liang Peng are going to do an important experiment. They have made something. Today is the day when the results will be released. If Li Xin were at the scene, he would definitely recognize it at a glance. , that thing is a simple hand-cranked disc generator, yes, the test the two of them are going to do today is to verify the existence of electricity.

Zhao Xi said: "Brother Liang, we have worked hard for a year to make this generator. Today's success or failure depends on this."

Liang Peng nodded and said: "Yes, in order to make wires and discs, we melted a lot of copper coins. For this, we were often scolded by the craftsmen."

Zhao Xi asked: "Brother Liang, has the light bulb on the other end been connected?"

Liang Peng replied: "Brother Zhao, everything is connected. Everything is ready. We can start testing."

Zhao Xi said: "Okay, let me start shaking it."

Zhao Xi began to turn the disk. As the disk rotated faster and faster, a current began to slowly flow out through the copper wire and into the light bulb, and the light bulb began to light up brightly or dimly.

Liang Peng jumped up excitedly and said: "Brother Zhao, it's bright, it's bright, we succeeded. Everything written in the Lord's book is true, there is really electricity."

Zhao Xi nodded and said: "Well, I have seen it, but spinning the disk is really tiring. In the future, I will definitely make a generator that does not require manpower."

Liang Peng said: "Let's quickly gather the others, including the lord, and let them all see the results of our experiment."

Zhao Xi replied: "Okay, let's go separately."

After Li Xin got the news, he took his younger sisters Li Jing and Liang Hongyu to the place where Zhao Xi and Liang Peng were experimenting.

After the three of them arrived at the place, they saw that many Confucian scholars had arrived, including Liu Yi.

Li Xin stepped forward and said, "Liu Yi, why are so many people here?"

Liu Yi replied: "My lord and madam, everyone wants to come and see the experimental results of Zhao Xi and the others."

Li Xin nodded and said, "Then organize everyone and ask Zhao Xi and the others to move things outside for testing."

Liu Yi cupped his fists and said, "Yes, lord, my subordinates know."

After Liu Yi left, Li Jing asked: "Brother, why are there so many people here? What are they going to do?"

Li Xin smiled and said: "Sister, wait a moment, I have something good for you to see today."

After a while, after everyone was seated, Zhao Xi moved out a table, and then moved out a hand-operated disc generator and light bulbs.

Li Xin stepped forward to take a look and said, "I didn't expect you guys to actually make this thing."

Zhao Xi scratched his head and said, "My lord, these are all things written in the book. We just melted some copper coins and followed them. It's not difficult."

Li Xin waved his hand and said: "Although it is all written in the book I gave you, it is not easy for you to make it. No matter what the result is today, I will reimburse you for your expenses."

Zhao Xi cupped his fists and said, "Thank you, Lord."

Li Xin looked at the light bulb and asked, "You also made this light bulb."

Zhao Xi replied: "Yes, we asked people from Liulicongfang to make the light bulbs."

Li Xin nodded and said: "Well, what do you use for the filament?"

Zhao Xi said: "My lord's book says that it is best to use tungsten wire, but we can't find tungsten wire and don't know tungsten ore, so we can only use carbonized bamboo wire instead."

Li Xin asked: "Well, the air in this light bulb has been evacuated."

Zhao Xi replied: "Yes, we made a simple air extractor according to the instructions in the book and evacuated all the air in the bulb."

Li Xin asked again: "Since you have made the air pump, have you done any experiments on vacuum and atmospheric pressure?" Li Xin remembered that German physicist Otto von Guericke invented the air pump. Later, many experiments were conducted on vacuum and atmospheric pressure, the most famous of which was the Magdeburg Hemisphere Experiment, which proved the existence of atmospheric pressure.

Zhao Xi scratched his head and said with a smile: "My lord, I haven't done it yet. I am just busy making light bulbs and generators to verify the existence of electricity. I haven't had time to do many other experiments yet."

Li Xin said: "Well, if you need to do any tests in the future, you can come directly to XX. If XX is gone, go to Liu Yi. The materials for the test will be provided by XX, but you can't waste the materials. You need to use as much as you want each time." For the record, after all, we’re not very wealthy right now.”

Zhao Xi clasped his fists and said, "Yes, my lord, I understand."

Li Xin said to Liu Yi: "You should also tell other Confucian scholars who need to do experiments about this."

Liu Yi replied: "Yes, my lord."

Li Xin nodded and said, "Okay, Zhao Xi, let's start the experiment."

Following Li Xin's order, Zhao Xi and Liang Peng connected the circuit and began to rotate the disk. As the disk accelerated, the light bulb slowly became brighter.

Li Jing said in surprise: "Brother, look, that glass ball has become brighter."

Li Xin nodded and said: "Well, not bad. Although the brightness is not quite enough, at least it is bright. The test results are still very successful."
